About the Vow of Peace cheese (hot damn that is a lot of AC)...
Your AC will only go up to 34, since you don't have a natural armor bonus from Vow of Poverty to improve. (people are assumed to have a natural armor bonus of +0, but this is not from Vow of Poverty). However, you will get that bonus when you hit level 8 and actually get the natural armor bonus. As for shattering peoples' equipment, as long as there is a person using it, the item just uses its owner's save bonus. So your opponents will need to beat your 34 AC and pass a DC 12 (easy) fort save to hit you. Also, bear in mind that your Calming Aura thing is going to affect your teammates, too; in fact, in might affect your allies more often than it affects your enemies. Also, since it's mind affecting, it won't work on vermin (or similar)... which you can't fight, since they are alive. You are officially worse than useless to have in a fight to the death against a lab rat.
As for RAM's summon-KO thing, to prevent loophole abuse, if your summoned creatures break Van's vow for you, they will take the full penalty, and you will take the same penalty with halved duration (since summoning creatures to fight for you is a rather blatant offensive maneuver, but is TECHNICALLY not an instance of "you killing someone").
The biggest problem with these vows is that if you break them, they don't come back, ever. So Van is going to have to do his darnedest to incapacitate you if you try to kill someone he's captured. Also, I'm considering "letting prisoners starve/dehydrate to death" as deliberate infliction of harm. And, if Van starts being too deliberately ignorant, I might just have the in-universe gods show up and give him a warning. ("This is the EIGHTEENTH GODDAMN TIME you have "gone scouting" immediately after incapacitating an enemy, allowing your allies to execute him. Smarten up.")
Finally, I will have the list of everyone who gets story experience for helping Akoth up tomorrow.
